A Versatile Mid-Size Wheel for Carts and Equipment

The 3.5 inch wheel is a popular middle ground: large enough to roll smoothly over floor seams and thresholds, small enough to keep equipment low and compact. It fits service carts, utility carts, racks, and light industrial equipment where a 3 inch wheel feels too small and a 4 inch raises the deck too high. With top plate and stem mounting options, it drops into most existing equipment without modification.

Frequently Asked Questions About 3.5 Inch Casters

3.5 inch casters are common on service carts, utility carts, equipment stands, and light industrial racks. The wheel is large enough to roll over thresholds and floor seams smoothly but small enough to keep the equipment deck low and compact.

Most 3.5 inch casters carry about 210 to 300 lbs each, depending on the wheel material and construction. For a four-caster cart, that is roughly 600 to 900 lbs of usable capacity after a safety margin. Divide your total load across the casters and size up if in doubt.

Yes. Brake models are available in this size, including total-lock brakes that stop both the wheel and the swivel. A common setup is two brake casters and two standard swivel casters per cart, so you can park securely while keeping the cart easy to steer.

A top plate caster bolts to a flat surface using four holes, the most common and secure mount. A stem caster inserts into a tube leg, socket, or threaded receiver, ideal for furniture and tubular equipment. Both are offered in this 3.5 inch size.

3.5 Inch Casters: Rubber, Polyurethane, and Polyolefin Wheels

Rubber wheels roll quietly and cushion the load, ideal for office and retail environments. Polyurethane carries more weight, resists oils and chemicals, and protects floors, a strong all-around choice. Polyolefin is economical and handles wet or washdown conditions well. All three are available in this 3.5 inch size, so you can match the wheel to your floor and load.

These 3.5 inch casters carry roughly 210 to 300 lbs per caster and come in top plate, threaded stem, expanding adapter, and grip ring mounts. Top plate models bolt to a flat surface, while stem models insert into tube legs or sockets. Swivel, rigid, and locking brake versions let you build a complete set that steers, rolls straight, and parks where you need it.
